Installation
Procedure
Bosch Rexroth AG, A15V(L)O Series 11, RE 92511-01-B/2019-10-09
To connect the axial piston unit to the hydraulic system:
1.
Remove the protective plugs and/or threaded plugs from the ports where the
connections should be made according to the hydraulic circuit diagram.
2.
Make sure the sealing surfaces of the hydraulic ports and functional surfaces are
not damaged.
3.
Use only clean hydraulic lines or flush them before installation.
(Observe chapter 7.5 "Performing flushing cycle" on page 45 when you flush
the hydraulic system.)
4.
Connect the lines in accordance with the installation drawing and the machine
or system circuit diagram. Check that all ports are connected or plugged with
threaded plugs. With inside-reservoir installation, the housing of the axial piston
unit must be filled before fitting the lines and filling the reservoir with hydraulic
fluid.
5.
Properly tighten the fittings (observe tightening torques!). Mark all properly
tightened fittings, e.g. with a permanent marker.
6.
Check all pipes and hose lines and every combination of connecting pieces,
couplings or connecting points with hoses or pipes to ensure they are in safe
working condition.
7.4.9 Electrically connecting the axial piston unit
Pressure increase due to excessive control current with D2 controller!
Applying current above the limit of 750 mA to the D2 controller via proportional
solenoid results in an impermissible increase in pressure.
▶
Make sure that the proportional solenoid is not energized to more than the
permissible current limit of 750 mA (see also data sheet 92511 D2 controller
technical data).
Short circuit due to penetrating hydraulic fluid!
Fluid can penetrate the product and cause a short circuit!
▶
Do not install axial piston units with electric components (e.g. electric controls,
sensors) in a reservoir below the fluid level (inside-reservoir installation).
The machine/system manufacturer is responsible for electric control layout.
Electrically controlled axial piston units must be connected in accordance with the
electrical circuit diagram for the machine/system.
For axial piston units with electrical control and/or mounted sensors, observe the
information in data sheet 92511, e.g.:
• Permissible voltage range
• Permissible current
• Correct pin assignment
• Recommended electrical control units
